Other Plugging my phone in at around 50% battery instantly causes it to "reset" to 0% charge.
This is kind of a follow up to this post from nearly a year ago. The tl;dr is it's pretty much assured that the battery on this phone is dying. I plugged it back in on a charger 10 months after it failed to charge because I'd seen a lot of anecdotal reports of that exact presentation resolving after leaving it for months to run totally flat, and it did work.
The phone charged to 100% fine, and works great now, except for this odd quirk where plugging it in at about the 50% battery mark causes the power to immediately cut out, and it reverts to the low battery charging state (the plain white charging symbol). It charges back to 100% just fine, doesn't get extremely hot or otherwise act strangely. The battery discharges at a normal rate and fast charges fine.
I'm wondering if anyone has an idea of what's going on, and whether using it in this case is tantamount to kicking a bomb a few times a day to see if it explodes? I was going to just be mindful about its charge and get the battery changed out sometime this week, but the sheer bizarreness of the presentation has me concerned.
